Knockdown of SCAMP1 expression reduced tumor cell growth, invasion, epithelial‑mesenchymal transition (EMT), and improved sensitivity to 5-fluorouracil (5-FU) in vitro and inhibited tumor cell xenograft growth in nude mice...The data from the current study demonstrated an oncogenic SCAMP1 activity in PDAC. Further study will investigate SCAMP1 as a tumor biomarker and novel target in control of PDAC clinically.
